OK, so I was determined to make it happen and found a way. Basically these are just a couple of short vids that were left over pics from when I had the lightning trigger running so the pics weren't taken at timed intervals but it seems to have worked out alright. I want to try it with a bit more purpose next time, it'll give me an excuse to work out how my digital shutter cable works too.
